TSL250R, TSL251R,
TSL252R
Light-to-Voltage Optical Sensors
General Description
The TSL250R, TSL251R, and TSL252R are light-to-voltage optical
sensors, each combining a photodiode and a transimpedance
amplifier (feedback resistor = 16MΩ, 8MΩ, and 2.8MΩ
respectively) on a single monolithic IC. Output voltage is
directly proportional to the light intensity (irradiance) on the
photodiode. These devices have improved amplifier
offset-voltage stability and low power consumption and are
supplied in a 3-lead clear plastic sidelooker package with an
integral lens. When supplied in the lead (Pb) free package, the
device is RoHS compliant.
Ordering Information and Content Guide appear at end of
datasheet.

Note(s):
1. Measurements are made with RL = 10kΩ between output and ground.
2. Optical measurements are made using small-angle incident radiation from an LED optical source.
3. The input irradiance E e is supplied by an AlInGaP LED with peak wavelength λ p = 635nm.
4. The input irradiance Ee is supplied by an GaAlAs LED with peak wavelength λ p = 880nm.
5. Irradiance responsivity is characterized over the range V O = 0.05 to 2.9V. The best-fit straight line of Output Voltage VO versus irradiance Ee over this range will typically have a positive extrapolated
VO value forEe = 0.

RoHS Compliant & ams Green
Statement
RoHS: The term RoHS compliant means that ams AG products
fully comply with current RoHS directives. Our semiconductor
products do not contain any chemicals for all 6 substance
categories, including the requirement that lead not exceed
0.1% by weight in homogeneous materials. Where designed to
be soldered at high temperatures, RoHS compliant products are
suitable for use in specified lead-free processes.
ams Green (RoHS compliant and no Sb/Br): ams Green
defines that in addition to RoHS compliance, our products are
free of Bromine (Br) and Antimony (Sb) based flame retardants
(Br or Sb do not exceed 0.1% by weight in homogeneous
material).
Important Information: The information provided in this
statement represents ams AG knowledge and belief as of the
